648c7fb16f lib/crc: make arch-optimized code use subsys_initcall 
Make the architecture-optimized CRC code do its CPU feature checks in
subsys_initcalls instead of arch_initcalls.  This makes it consistent
with arch/*/lib/crypto/ and ensures that it runs after initcalls that
possibly could be a prerequisite for kernel-mode FPU, such as x86's
xfd_update_static_branch() and loongarch's init_euen_mask().

Note: as far as I can tell, x86's xfd_update_static_branch() isn't
*actually* needed for kernel-mode FPU.  loongarch's init_euen_mask() is
needed to enable save/restore of the vector registers, but loongarch
doesn't yet have any CRC or crypto code that uses vector registers
anyway.  Regardless, let's be consistent with arch/*/lib/crypto/ and
robust against any potential future dependency on an arch_initcall.

436490e868 powerpc/crc: drop "glue" from filenames 
The use of the term "glue" in filenames is a Crypto API-ism that rarely
shows up elsewhere in lib/ or arch/*/lib/.  I think adopting it there
was a mistake.  The library just uses standard functions, so the amount
of code that could be considered "glue" is quite small.  And while often
the C functions just wrap the assembly functions, there are also cases
like crc32c_arch() in arch/x86/lib/crc32-glue.c that blur the line by
in-lining the actual implementation into the C function.  That's not
"glue code", but rather the actual code.

Therefore, let's drop "glue" from the filenames and instead use e.g.
crc32.c instead of crc32-glue.c.
